I found a slight bug: If you ask for a hint on the egg question, the paper stays glued to your face until you die and restart the area.
Update: The same is true for all papers (Both hints and instruction) and they just layer on top of each other if you don't die between recieving them.
Update 2: Through pressing every button on my keyboard, I discovered that they can be cleared via the X key. It'd be a good idea to add that to the list of controls in the tutorial page, to avoid confusion in the future
